I've been able to fix two HP laptops just by watching your videos, thank you for giving us confidence to work on these electronics coz you make it look so easy

[@MikeGregos]

I was gifted my first, cheap reflow station today. I have some soldering skills for fixing guitar patch cables, but never used the air before. I was able to fix a ssd, firestick remote and small audio mixer within the first hour. Love your channel, listening to you talk, explaining your work and sometimes making fun of the comments..."Seriously, what planet are you on?" was on a recently watched video. I also caught myself narrating my fix attempts (in your voice) and saying things like, "Awesome work" when I turned off the air and inspected the pins by gently pushing on them. I am pumped to learn more and need a microscope. My old man eyes can't see well. Keep doing what you're doing.

[@stefanlechner]

Amazing work. I bet you are really happy to have "big boss". You and your family does such a great work in your shop. Greets

[@fteoOpty64]

Your "big boss" has good eyes and dexterous hands for his age. Great to see an old timer doing tech things these days. Good on him

[@robertoruiz7069]

ALEX,this was one of your best video's. 1st it was short and to the point,and every single thing you did ,i understood why.I'm a collector of older laptops and just like to mess with them.for fun only,i take them apart. THIS video will give a a chance to learn and hopefully get one to work again.So thank you so much for SHARING your vast knowledge in a simple way with no BS magic.AND hello from the BAY AREA!!

Amazing work as always, Wish there was someone as talented in the UK :)

[@raymorales8448]

I did bench work for 20 years on pro audio equipment love your videos, never thought to use a thermal cam to diagnose great tip for me, just sent you an iPad hopefully it will be another success for you, keep the videos coming.

[@Pr0E]

One of the switches on my keyboard broke recently and inspired by this channel I decided to try soldering it myself. I managed to get another broken one as a donor and to practice on, after a few tries I got the keyboard working perfectly. Thanks for the great educational content!

I wish you luck, but if you're any good put ads online it's a service that's not available everywhere. Tbh when things start going you'll be hiding like me, I wouldn't be mad enough to run ads (;

[@tomschupbach2200]

Yeah, except one of them would be a rabbit hole with no ending. Took me a long time to know when to hold 'em and when to fold 'em, thanks to Alex's videos helping me figure that out!

Dobra robota, jak zawsze. Kupiłem córce laptopa asusa pół roku temu, zobaczymy ile będzie działał...

[@HaciendoCosasRaras00]

I´ve been following your channel for a while, and for sure is the best about microelectronic soldering and repair. I wonder what porcentage of the motherboards (laptop/desktop) repairs are cap/mosfet short circuit related? Regards and keep the good work!

[@mqtlfy]

great work as always mate, thank you

[@rfr653]

Good job mate 👍

[@mikesmith9972]

I like watching your videos. They are very inspirational. I have limited experience in the technical side of electronic repair. However I'm more than proficient in soldering as I have been building and flying quad copters for well over 10 years now. I am interested in trying my hand in the electronic repair industry. What would you recommend for a start up? What tools/ equipment should i have? I have the soldering station, hot air reflow unit, power supply unit and a other few select gadgets for utility. Perhaps aquiring the FLIR camera and a good set of bits for disassembly would be a good addition? Any recommendations?Thank you for your work.

[@Fix_8080]

Amazing! 👏🏼👏🏼👏🏼👏🏼 Thanks for share it!

[@mazharkhan9595]

I learned on this channel that Asus laptops have a lot of issues or they sell a lot of units hence the frequency of more faulty laptops either way ill be avoiding them in the future.

[@brandonkick]

Not just ASUS. All consumer grade laptops are prone to it. Buy a business grade machine, one that offers a really good warranty, and your golden. Why? Manufacturers design a better product when they offer a warranty with it that is of significant liability to them. They don't want to have to honor the warranty. So they build the laptop better. For the most part.

[@UhOhUmm]

They are popular and they are worth fixing, that's why you're seeing them. If a budget laptop explodes no one is going to pay hundreds of dollars for board repair. Just get a new one instead.

[@shkoahmad3031]

Amazing style of sharing his skills and teach the other people that is why god is always helping these kind of people

[@giuseppet7503]

Hello dude, you are the number one, can i ask how did you know the value of the caps?

[@gennarosole8780]

This is a long shot but would you have any idea how to reset the cmos on one of these boards? I dont see a battery or a jumper. Is there a chip i have to unsolder or short out or something?

[@jyrkiunhola5181]

The repairs you are doing are the top of everything but how high are your stress level...i wonder?

[@michaels8336]

How do you know which caps to use as no value is written on them?

[@Professorke]

I also wonder this?

[@xKateshi]

He repairs a lot of asus laptops, maybe that's how

[@cjay2]

He probably measured one of the two caps. There are only a couple of common values used for that bypass function.

[@Humajk0]

Wanted to ask the same... :D

[@6pack1204]

Alex, how do you know the value of the shorting caps?

[@joseramos3076]

Hello Alex, do you sell out the USA, I mean, Latino america, Venezuela, colombia? It would be great.

[@fraenkiboii]

I started watching Bosch (series). Recently they mentioned northridge ... is it the area where you are located in LA?

[@echolitis]

Hey, I have the same laptop with the same problem. How much would this cost if I ship it to you?

[@discoopotato1122]

bigboss already disassembled the board.. I've heard that sentence after decades :)

[@Denise_in_progress]

If only we can afford a thermal cam that costs around 800 or more from flirr we could do the same quick methode but unfortunately it's too expensive so we are longer busy with finding the problem component(s) by schematic if there is one. If no schematic available we then follow the powerrail and do it the old fashion way and then it takes hours to find the problem. I really hope they make thermal cams pricing not so high so it's affordable for everyone. But nice job one again.

[@HaciendoCosasRaras00]

Hi, there are a couple of tricks to find a shorted component without a thermal camera, use of isopropyl alcohol, lighter fluid or rosin for example. Regards!

[@dbibby1988]

Is this considered a cheaper or dearer fix? I am only asking because I have a gaming laptop which has the same symptoms as this video and it is in for repair. Its driving me crazy waiting to see if it is fixable and the cost of the fix.

[@OMAR7]

I really love your content but seriously you need to stop calling disaster repair attempts HIROSHIMA, imagine someone keeps calling it Beirut, I know you addressed this in a previous videos but I think it won't hurt to stop calling it that. BTW great video as always

How about no.

Can anyone explain what is special/unique about Asus laptops that they suffer the most from a short? Why does your channel only gets Asus laptops for repair (mostly)? And what can a customer do to prevent such shorting?

No problema senhor eu estendi sou brasileiro ( I understand, i'm braziliam) 😁

Could you explain what people are doing to create this problem ? If it is possible. Would be good to know , or is it just flat-out bad design/low quality caps ?

[@gamersanditparadise]

Yeah, I am curious too. How to prevent shorts? I also have an Asus Zephyrus G14 laptop and I am worried.

[@mohamadmoheb9372]

hey im kind of a begginer, why do you inject voltage? isnt it the same as plugging in the charger in this laptop's case?

[@Hereford1642]

The 19V voltage supply from your charger will pass through usually two mosfets before feeding the rest of the board and if your laptop detects an excess current it will turn one of these mosfets off so no current will continue for more than a brief instant when you plug in. Note the resistor to the right of the mosfet. A very low value resistor which is almost certainly used by the laptop to measure the current being drawn. He is injecting a much lower voltage - 1.2 or 1.5 after the two protection mosfets. A low enough voltage not to damage anything else but also enough to drive some current through whatever is short circuited and produce some heat to detect with his camera (you can use your finger too or some alcohol). He is not trying to turn the machine on at all - it is purely to see what warms up due to being short circuit. The typical path is ... Charger port - mosfet - mosfet - resistor to detect current - rest of the board.
